Abstract

Existen métodos para determinar la o las claves utilizadas por el módulo que analiza los datos que entran o salen de él en el momento de la utilización del módulo de encriptación-desencriptación. Para paliar este defecto, el método multi-módulos propuesto consiste en que el módulo corriente abajo comience sus operaciones para encriptar-desencriptar cuando esté disponible una parte de los resultados del módulo corriente arriba.There are methods to determine the key (s) used by the module that analyzes the data entering or leaving it at the time of using the encryption-decryption module. To alleviate this defect, the proposed multi-module method is that the downstream module begins its operations to encrypt-decrypt when a part of the results of the upstream module is available.
